@usesigil/custody

TEE wallet custody adapters for Sigil — hardware-enclave signing where the private key never leaves the TEE.

Adapters

| Subpath | Provider | TEE | |---------|----------|-----| | @usesigil/custody/crossmint | Crossmint | Intel TDX | | @usesigil/custody/privy | Privy | AWS Nitro Enclave | | @usesigil/custody/turnkey | Turnkey | Secure Infrastructure |

Install

npm install @usesigil/custody

Usage

import { crossmint } from "@usesigil/custody/crossmint";
import { privy } from "@usesigil/custody/privy";
import { turnkey } from "@usesigil/custody/turnkey";

// Create a TEE-backed wallet
const wallet = await crossmint({ apiKey: "sk_..." });

// Use with Sigil's shieldWallet
import { shieldWallet } from "@usesigil/kit";
const shielded = shieldWallet(wallet, { maxSpend: "500 USDC/day" });

Each adapter also supports zero-config from environment variables:

import { crossmintFromEnv } from "@usesigil/custody/crossmint";
import { privyFromEnv } from "@usesigil/custody/privy";
import { turnkeyFromEnv } from "@usesigil/custody/turnkey";
